title: Nerve transfer to the triceps after brachial plexus injury: report of four cases.
abstract: These case reports review the clinical outcomes of 4 patients who underwent nerve transfer to a triceps motor branch of the radial nerve. Mean follow-up was 26 ± 15 months. Two patients had a transfer using an ulnar nerve fascicle to the flexor carpi ulnaris muscle, yielding a motor recovery of grade M5 elbow extension strength in one case and M4+ in the other. In 1 patient, a thoracodorsal nerve branch was used as the donor; this patient recovered M4 strength. One patient had a transfer using a radial nerve fascicle to the extensor carpi radialis longus muscle and recovered M5 strength. These outcomes indicate that expendable fascicles of the ulnar, thoracodorsal, and radial nerves are viable donors in the surgical reconstruction of elbow extension.
